Icicles are formed when rooftop snow melts, then refreezes as it attempts to flow off the roof. When that melted snow gets to the eaves and gutters, there is no more warmth coming from underneath, so it freezes. Poor insulation and ventilation leads to more and more snow melting, which is when ice dams can form.

Do gutters cause ice dams?

An ice dam forms when the roof over the attic gets warm enough to melt the underside of the layer of snow on the roof. Gutters at the eaves can also trap snow and ice. If snow and ice build up high enough in the gutter, it can provide a foundation for an ice dam.

How do you knock off icicles?
